The billionaire entrepreneur was featured in a promotional video for the event at which the first lab-produced beef burger was unveiled, although he was not described as a benefactor.

In the video, he says: "I like to look at technology opportunities where the technology seems like it's on the cusp of viability".

He also says he supports the research for animal welfare reasons: "When you see how these cows are treated, it's certainly something I'm not comfortable with."
